Astride the giant coral reef which extends into Belize lie the Bay Islands of Roatán, Utila and Guanaja. Fringed with palm-shaded beaches and lapped by warm, glass-clear Caribbean waters they attract divers, snorkellers and barefoot holiday-makers in large numbers. The islands have a vivid history. Once the base for European pirate attacks on shipping, they were colonised by Carib Indians, former African slaves, and Garifuna communities, creating today’s cultural melting pot to which Honduran Latino immigrants are now adding their influence. It’s a laid-back ambience, beloved of budget travellers and sun-worshippers alike.   On the mainland opposite are a few agreeable resorts: Tela, within reach of glorious beaches, is the most significant.
